Probing the activity and stability of MoO2 surface nanorod arrays for hydrogen evolution in an anion exchange membrane multi-cell water electrolysis stack

An active and stable hydrogen evolution electrocatalyst composed of MoO 2 surface nanorod arrays was prepared using high-temperature reductive annealing. Electrodes with an area of 78.5 cm 2 were evaluated in a three-cell AEM electrolyser stack.
